Hi-Fi failure helps to brighten beer
BRIGHTER, clearer beer could be on the way thanks to a superfine filter that owes its existence to the failure of a decade-old recording technology. In the early 1990s, Philips of the Netherlands developed the Digital Compact Cassette tape format, which was designed to give CD-quality sound on standard magnetic tapes. DCC used record/playback... view more... (2004-07-07)
Caltech scientists predict greater longevity for planets with life
Roughly a billion years from now, the ever-increasing radiation from the sun will have heated Earth into inhabitability; the carbon dioxide in the atmosphere that serves as food for plant life will disappear, pulled out by the weathering of rocks; the oceans will evaporate; and all living things will disappear. view more (2009-06-15)
Researchers perform multi-century high-resolution climate simulations
Using state-of-the-art supercomputers, Lawrence Livermore National Laboratory climate scientists have performed a 400-year high-resolution global ocean-atmosphere simulation with results that are more similar to actual observations of surface winds and sea surface temperatures. view more (2008-04-02)
Recipe for a storm: The ingredients for more powerful Atlantic hurricanes
As the world warms, the interaction between the Atlantic Ocean and atmosphere may be the recipe for stronger, more frequent hurricanes. view more (2007-11-30)
Central American fires impact US air quality and climate
Scientists using NASA satellites and computer models have shown that pollutants from Central American biomass burning can influence air quality and climate in the United States. view more (2006-10-11)
Magnetic field uses sound waves to ignite sun's ring of fire
Sound waves escaping the sun's interior create fountains of hot gas that shape and power a thin region of the sun's atmosphere which appears as a ruby red "ring of fire" around the moon during a total solar eclipse, according to research funded by the National Science Foundation (NSF) and NASA. view more (2007-05-30)
Discovery of methane reveals Mars is not a dead planet
A team of NASA and university scientists has achieved the first definitive detection of methane in the atmosphere of Mars. This discovery indicates the planet is either biologically or geologically active. view more (2009-01-16)
Growth in the global carbon budget
Today the new Global Carbon Budget was launched simultaneously by Global Carbon Project co-chair Michael Raupach in France at the Paris Observatory, and in the USA at Capitol Hill, Washington by GCP Executive Director Pep Canadell. view more (2008-09-25)
Ozone layer decline leveling off, according to new study
A new global study involving long-term data from satellites and ground stations indicates Earth's ozone layer, while still severely depleted following decades of thinning from industrial chemicals in the atmosphere, is no longer in decline. view more (2005-08-30)
'Ultra-primitive' particles found in comet dust
Dust samples collected by high-flying aircraft in the upper atmosphere have yielded an unexpectedly rich trove of relicts from the ancient cosmos, report scientists from the Carnegie Institution. view more (2009-11-03)
"Nanominerals" Influence Earth Systems from Ocean to Atmosphere to Biosphere
The ubiquity of tiny particles of minerals--mineral nanoparticles--in oceans and rivers, atmosphere and soils, and in living cells are providing scientists with new ways of understanding Earth's workings. Our planet's physical, chemical, and biological processes are influenced or driven by the properties of these minerals. view more (2008-03-24)
New Satellite To Study Explosive Solar Flares
A small NASA spacecraft, dedicated solely to the study of high energy processes in gigantic explosions in the atmosphere of the Sun, is scheduled to be launched early next week. Although the 293 kg (645 lb) satellite, known as the High Energy Solar Spectroscopic Imager (HESSI), carries only one scientific instrument, it will make a major... view more... (2002-01-31)
Field project seeks clues to climate change in remote atmospheric region
Scientists are deploying an advanced research aircraft to study a region of the atmosphere that influences climate change by affecting the amount of solar heat that reaches Earth's surface. view more (2008-06-13)
Scientists Recreate Martian Environment
Scientists at the University of Leicester's Space Research Centre are recreating the hostile environment found on Mars in their laboratory, with a device known as the Martian Environment Simulator (MES). The machine reproduces the temperature, air pressure and unbreathable atmosphere known to exist on Mars. The MES is currently being used to test... view more... (2002-05-31)
How rusty is the Earth?
An iron object lying around outside quickly turns rusty. Iron metal always has to be combined with some other elements or coated with paint to stop it corroding. The reason for this is that iron metal is unstable in the presence of the oxygen in the Earth's atmosphere. It reacts with the iron to produce ferric iron, a form of iron that exists in... view more... (2004-06-10)
Climate models need deeper roots, scientists say
By soaking up moisture with their roots and later releasing it from their leaves, plants play an active role in regulating the climate. In fact, in vegetated ecosystems, plants are the primary channels that connect the soil to the atmosphere, with plant roots controlling the below-ground dynamics. view more (2005-12-06)
Titan's icy climate mimics Earth's tropics
If space travelers ever visit Saturn's largest moon, they will find a tropical world where temperatures plunge to minus 274 degrees Fahrenheit, methane rains from the sky and dunes of ice or tar cover the planet's most arid regions. These conditions reflect a cold mirror image of Earth's tropical climate. view more (2007-10-03)
University of the Basque Country researchers believe methane storms on Titan
The detailed exploration of Titan with space missions began a couple of years ago and the presence of bright polar clouds and dry riverbeds on this satellite of Saturn has intrigued astronomers ever since. view more (2006-07-31)
Saturn's winds are variable
A team of astrophysicists at the University of the Basque Country has detected, for the first time ever, changes in Saturn's winds. The research has merited front page coverage in the scientific magazine, Nature. The winds blowing around Saturn and Jupiter are special. Unlike those of the rest of the planets, these move in an eastwards direction... view more... (2003-06-09)
Protective Storm in Space - a new explanation for the death of the dinosaurs
A shower of matter from space millions of years ago could have led to drastic changes in the Earth's climate, followed by the extinction of life on a massive scale, which also killed off the dinosaurs. This at least is a theory put forward by scientists from the University of Bonn. Normally, the solar wind acts as a shield against showers of... view more... (2002-06-04)
